CYLINDER FOR CLOVER-'HULLERS.

SPECIFICATION forming part of Letters Patent No. 316,308, dated April21, 1885.

Application filed January 20, 1885. (N0 model.)

T0 00% whom it may concern.-

Be it known that I, FREDERICK STRoBEL, a citizen of the United States,and a resident of Marion, in the county of Marion and State of Ohio,have invented certain new and useful Improvements in Cylinders forGlover-Hullers; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which Figure 1 is a perspective View of myimproved cylinder for clover-hullers. Fig. 2 is a perspective View ofone of the sections composing the same. Fig. 8 is alongitudinalsectional view of the said part or section, and Fig 4 is a transversesectional view taken on the line a; m in Fig, 3.

The same letters refer to the same parts in all the figures.

My invention has relation to cylinders for clover-hullers; and itconsists in the improved construction and combination of parts of thesame, as hereinafter more fully described and claimed.

In the drawings hereto annexed, A designates the frame of my improvedcylinder, which consists of a series of parallel beams or bars, B B,secured to and connected by suitable heads or ends, 0 O, to which thesaid beams or bars are equidistantly secured by means of bolts, or inany other suitable manner.

D is one of the cylinder-sections, which consists of a curved plate orcasting the ends of which are provided with flanges E E, havingperforations F to receive bolts whereby it may be connected to thecylinder-frame. The outer convex side of the said plate or casting isprovided with longitudinal ridges G G, arranged parallel to each other,and having vertically-corrugated sides. The said ridges are subdividedby central grooves, H, into sections I I, the face of each of which isprovided with a sharp notch, J, whereby it is rendered more effective inuse.

The sections D D, of which any suitable or desirable number may be used,are to be bolted or otherwise secured to the frame in alter-- natingrows substantially as secured in Fig. l of the drawings. This device isbest adapted for use in connection with the concave for which I havemade application for Letters Patent at the time of filing thisapplication; and its uses and advantages will not fail to be understoodby those skilled in the art to which it appertains Without furtherdescription.

Having thus described my invention,I claim and desire to secure byLetters Patent of the United States- 1. In a cylinder forclover-hullers, the combination, with a suitable frame, of thehereindescribed sections, consistingof curved plates having longitudinalvertically corrugated ridges provided with central transverse grooves,and having sharp notches in' their outer edges or faces, substantiallyas and for the purpose set forth.

2. The combination, with the cylinderframe consisting of a series ofparallel equidistant bars and suitable heads or ends, of the toothedsections consisting of curved plates having perforated flanges and boltswhereby they are attached to the bars of the frame, said toothed platesbeing attached to the frame in alternate intersecting rows,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

FREDERICK STROBEL.
